Summary
Rapid Acceleration of Diagnostics (RADx®) Tech was the key diagnostics component of a three-pronged national strategy, including vaccines and therapeutics, to respond to the COVID-19 pandemic. Unprecedented in the scale of its mission, its budget, its accelerated time frame, the extent of cross-government agency collaboration and information exchange, and the blending of business, academic, and investment best practices, RAD Tech successfully launched dozens of US Food and Drug Administration Emergency Use Authorization diagnostic tests, established a new model for rapidly translating diagnostic tests from the laboratory to the marketplace, and accelerated public acceptance of home-based diagnostic tests. This chapter provides an overview of the processes utilized by RADx Tech during the COVID-19 pandemic to improve clinical laboratory tests and identify, evaluate, support, validate, and commercialize innovative point-of-care and home-based tests that directly detected the presence of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) virus.

As part of the “America First” agenda discussed in his inaugural address, President Donald J. Trump promised that “[e]very decision” on trade, among other areas, would be “made to benefit American workers and American families.” During its first months, the Trump Administration made a number of trade moves apparently in connection with this “America First” trade agenda, including initiating national security investigations into steel and aluminum imports under Section 232 of the Trade Expansion Act of 1962 and preparing an “omnibus” report on trade deficits. The Trump Administration also took steps to alter U.S. treaty relationships, by withdrawing from the Trans-Pacific Partnership Agreement, announcing the renegotiation of the North American Free Trade Agreement, and requesting a special session of a joint committee created under the United States-Korea Free Trade Agreement. In August 2017, President Trump continued this course—and indicated a willingness to take unilateral action against U.S. trading partners—by signing a presidential memorandum directing the United States Trade Representative to determine whether China's treatment of U.S. intellectual property warranted investigation under Section 301 et seq. of the Trade Act of 1974.

After a little more than forty years of work related to the interplanetary plasma and the heliosphere the IAU's Commission 49 was formally discontinued in 2015. The commission started its work when the first spacecraft were launched to measure the solar wind in–situ away from Earth orbit, both inward and outward from 1 AU. It now hands over its activities to a new commission during an era of space research when Voyager 1 measures in–situ the parameters of the local interstellar medium at the edge of the heliosphere. The commission will be succeeded by C.E3 with a similar area of responsibility but with more focused specific tasks that the community intends to address during the coming several years. This report includes a short description of the motivation for this commission and of the historical context. It then describes work from 2012 to 2015 during the present solar cycle 24 that has been the weakest in the space era so far. It gave rise to a large number of studies on solar energetic particles and cosmic rays. Other studies addressed e.g. the variation of the solar wind structure and energetic particle fluxes on long time scales, the detection of dust in the solar wind and the Voyager measurements at the edge of the heliosphere. The research is based on measurements from spacecraft that are at present operational and motivated by the upcoming Solar Probe + and Solar Orbiter missions to explore the vicinity of the Sun. We also report here the progress on new and planned radio instruments and their importance for heliospheric studies. Contributors to this report are Carine Briand, Yoichiro Hanaoka, Eduard Kontar, David Lario, Ingrid Mann, John D. Richardson.

A survey of the Milky Way disk and the Magellanic System at the wavelengths of the 21-cm atomic hydrogen (H i) line and three 18-cm lines of the OH molecule will be carried out with the Australian Square Kilometre Array Pathfinder telescope. The survey will study the distribution of H i emission and absorption with unprecedented angular and velocity resolution, as well as molecular line thermal emission, absorption, and maser lines. The area to be covered includes the Galactic plane (|b| < 10°) at all declinations south of δ = +40°, spanning longitudes 167° through 360°to 79° at b = 0°, plus the entire area of the Magellanic Stream and Clouds, a total of 13 020 deg2. The brightness temperature sensitivity will be very good, typically σT≃ 1 K at resolution 30 arcsec and 1 km s−1. The survey has a wide spectrum of scientific goals, from studies of galaxy evolution to star formation, with particular contributions to understanding stellar wind kinematics, the thermal phases of the interstellar medium, the interaction between gas in the disk and halo, and the dynamical and thermal states of gas at various positions along the Magellanic Stream.

Experiments to explore the reactivity and thermochemistry of elementary transuranium sulfide molecules have been initiated to expand the basis for a fundamental understanding of actinide bonding, and to enable the development of advanced theoretical methodologies which will be of general applicability to more complex molecular systems. Bimolecular gas-phase reactions between transuranium actinide ions and neutral reagents are employed to obtain thermochemical information. The initial actinide sulfide studies have focused on obtaining the 298 K bond dissociation energy for the CmS+ ion, D[Cm+-S] = 475±37 kJ mol-1; from this result and an estimate of IE[CmS] ≈ IE[CmO] + 0.5 eV, we obtain D[Cm-S] = 563±64 kJ mol-1. The bond dissociation energies, D[Cm+-S] and D[Cm-S] are approximately 200 kJ mol-1 and 150 kJ mol-1 lower than for the corresponding oxides, CmO+ and CmO. The nature of the bonding in the CmS+ ion appears to be generally similar to that in other oxophilic metal sulfides. Comparisons with previous bond dissociation energies reported for ThS and US may suggest a difference in the An-S bonds for these early actinide sulfides as compared with CmS.

Electrospray ionization quadrupole ion trap mass spectrometry of the ammonium lanthanide(III) phosphomolybdate complex (NH4)11Ce(III)(PMo11O39)2 has been conducted revealing the Ce-POM complexes H2Ce(III)P2Mo22O753- and Ce(III)PMo11O382- as the primary Ce species in 10 mM solutions. From the complex isotopic fingerprints produced through the assembly of multiple molybdenum atoms, a transition metal with seven naturally occurring isotopes, the identities of larger ions were confirmed via successive collision induced dissociation (CID) studies of the gas phase ions. The result of these CID studies was the production of smaller ions with reduced molybdenum content, allowing for comparison between calculated and experimental isotopic distributions. CID studies also provided insights into favored fragmentation pathways. These studies provide a basis to explore speciation and ESI behavior of actinide cluster complexes.

Objective:
To identify the etiologic agent and risk factors associated with a hospital ward outbreak of gastroenteritis.
Setting:A regional referral hospital in upstate South Carolina.
Methods:We reviewed patient charts, surveyed staff, and tested stool from acutely ill persons. A case was defined as diarrhea and vomiting in a staff member or patient from January 5 to 13, 1996.
Results:The initial case occurred on January 5 in a staff nurse who subsequently was hospitalized on the ward and visited by many staff colleagues. The staff were at a significantly greater risk for gastroenteritis than were patients (28/89 [31%] vs 10/91 [11%]; relative risk [RR], 2.9; 95% confidence interval [CI95], 1.5-5.5). All 10 case-patients had been exposed to case-nurses (assigned nurses who were primary caretakers), and eight had documented exposure to case-nurses 1 to 2 days before their illness. Patients exposed to case-nurses had a significantly increased risk of illness (8/57 [14%] vs 0/32; RR, >4.5; CI95, undefined). Neither staff nor patients had significantly increased risk from food, water, ice, or exposure to case-patients. Electron microscopy identified small round-structured viruses (SRSVs) in nine of nine stool samples.
Conclusion:This nosocomial outbreak of gastroenteritis was likely caused by SRSVs introduced by a staff member and spread via person-to-person transmission from and among staff. The potential for spread of SRSV-associated gastroenteritis from and among staff should be considered in developing strategies to prevent similar outbreaks in hospital settings

In studies previously reported (1) it was found that milk of normal appearance from cows having a latent infection with Streptococcus agalactiae yielded less cheese than that from cows with normal udders. Milk from cows free from Str. agalactiae infection, yet classed as ‘abnormal’ on the basis of biochemical tests, behaved similarly. The lower yield appeared to result from the lower casein and solids-not-fat contents of these ‘mastitis’ milks. With a single exception, the quality of the cheese made from these milks was not inferior to that of cheese made from normal milks. These findings appeared to warrant the extension of the studies to ordinary cheese-factory milks.

Milk of normal appearance from cows having a latent infection with Str. agalactiae yielded definitely less cheese than that from normal cows. Milk from cows free from “agalactiae” infection, yet classed as “abnormal”, behaved similarly. The lowered yield appeared to result from the lower casein and solids-not-fat contents of these “mastitis” milks.
With a single exception, the cheese made from these “mastitis” milks were not inferior in quality to those made from normal milks.
